I've used both the Elevo and the Glass Science combo on our Vios and now it has no watermarks except for dun sa tight corners ng pero very minimal. The Rain Clear too is superb. I've just reapplied it yesterday. Huling gamit ko nun mga December 2009 pa, kahapon lang ulit ako nag-reapply. Ganoon siya katibay.

What cloth? Even the Terry towel will do. Just make sure the glass is completely dry.
i heard that we can use carnauba cleaner wax on windows (or the mothers chrome polish) to remove hardwater stains? is this true? how about using the claybar??
